Description

Crystal growth technology involves processes for the production of crystals essential for microelectronics, communication technologies, lasers and energy producing and energy saving technology. A deliberately added impurity is called an additive and in different industries these affect the process of crystal growth. Thus, understanding of interactions between additives and the crystallizing phases is important in different processes found in the lab, nature and in various industries.

本书介绍了添加剂在结晶过程中添加剂,晶体的生长和聚集过程中添加剂作用机制的广义描述,并获得了国际晶体增长组织总裁的认可。它是第一个介绍添加剂在实验室,自然和工业中遇到的不同结晶过程中作用的文本,如药物,食品和生物燃料。

A unique highlight of the book are chapters on the effect of additives on crystal growth processes, since the phenomena discussed is an issue of debate between researchers
